UNHAPPY first time shopper

Im a first time user of the online shopping store superbalist, I made my first purchase and was happy with the purchase, then while browsing the site, I found a belt to match the shoes of my first purchased. on my check I was charged a R60 delivery fee only minutes later after my first purchase which didn't have a fee based on the amount. I called their customer service line to add the second order to the first one so that im not charged the R60 delivery fee, and nobody could assist me. iI spoke to a supervisor named Zayaan Raban who told me that there is no way of combining the order even though its to the same address and if i wanted the second purchase i need to pay the R60 Del fee. that response really frustrated me and as a first time user, the experience has made very uncomfortable and caused me to NOT trust online shopping. so after a successful purchase , i will be cancelling the first order due to the in- flexibility in their procedures. Superbalist you just lost a customer.
